FIELD
[0002] This application relates to methods and systems for device
monitoring, and more specifically to methods and systems for
monitoring usage of electro-mechanical lifts.
BACKGROUND
[0003] Healthcare facilities have had a tremendous amount of back
injuries and workmen compensation claims, a majority of which were
caused by staff manually lifting and repositioning patients that
have at least some difficulty. Patients at times were also injured
by not being lifted or repositioned properly.
[0004] Today, most healthcare facilities have purchased
electro-mechanical lift equipment to help with the lifting and
repositioning of patients. The purchase of lifts did not
automatically reduce injuries at the rate the facilities had hoped.
Some staff still continue to perform lifts or repositioning without
use of the lift equipment.

DETAILED DESCRIPTION
[0013] Example methods and systems for lift monitoring are
described. In the following description, for purposes of
explanation, numerous specific details are set forth in order to
provide a thorough understanding of example embodiments. It will be
evident, however, to one of ordinary skill in the art that
embodiments of the invention may be practiced without these
specific details.
[0014] In an example embodiment, one or more measurement devices
are coupled to an electro-mechanical patient lift. The measurement
devices may make one or more readings of the electro-mechanical
patient lift. The readings may be provided to a transmitter. The
transmitter may then provided the readings to a monitoring
computing device, or may itself determine whether a lift has
occurred based on analysis of the readings. Once the determination
of whether a lift has occurred has been made, the resulting data
may be stored and used in a variety of ways.
[0015] In some embodiments, the methods and systems for lift
monitoring passively provide real-time information regarding use of
the lifting equipment directly to administrators of facilities that
have electro-mechanical patient lifts. In some embodiments, the use
of the methods and systems for lift monitoring may encourage
greater usage of the electro-mechanical patient lifts by equipment
operators at these facilities. In some embodiments, the use of the
methods and systems for lift monitoring may reduce injuries caused
by non-use or improper use of electro-mechanical patient lifts by
certain operators at these facilities that are not using the
electro-mechanical patient lifts as directed by an
administrator.
[0016] In some embodiments, the methods and systems may be used to
incrementally train staff in a facility to use electro-mechanical
patient lifts for one of a variety of different lift types. These
methods and systems may provide program management and increase
cultural change acceptance of greater use of electro-mechanical
patient lifts at facilities.
[0017] In some embodiments, the methods and systems may be used to
reduce the number of injuries relating to unassisted lifts. In
addition, the methods and systems may enable continued and greater
adoption of electro-mechanical patient lifts for a variety of
different lifting activities that are often performed in
facilities.
[0018] In some embodiments, the methods and systems may be used to
keep the correct number of slings and accessories in the unit or
department of the facility. This information may be used to reduce
facility costs in lost slings and improve outcomes (e.g., based on
a better chance the correct slings in the correct number will be in
the unit or department when needed).
[0019] In some embodiments, the methods and systems enable analysis
of lift data and then based on that analysis distribute usable data
to certain staff based on what the data is and the values of that
data. The methods and systems may then be used to provide
recommendations for improved methods of dealing with a subpar
outcome.
[0020] FIG. 1 is a block diagram of an example lift monitoring
system 100, according to an example embodiment. The lift monitoring
system 100 includes an electro-mechanical patient lift 102 that is
used in a hospital or other health care facility to assist in the
lifting or repositioning of a patient. The electro-mechanical
patient lift 102 may be a portable or nonportable lift. The
nonportable lift is usually affixed in a patient room of the
facility that is designated for use by certain patients that need
lift or repositioning assistance. The portable lifts are movable
from room to room in the facility. The portable lifts may include a
total care lift and/or a stand assist lift.
[0021] Data regarding use of the electro-mechanical patient lift
102 is obtained by use of one or more measuring devices 108. The
measuring devices 108 make readings during operation or
non-operation of the electro-mechanical patient lift 102. The
readings may be used to determine whether a patient lift using the
electro-mechanical patient lift 102 was performed. The measuring
devices 108 may be attached to, integrated with, or otherwise
coupled to the electro-mechanical patient lift 102. Examples of the
measuring devices 108 include relays, current sensors, load
sensors, vibration sensors, motion sensors, or the like. Other
types of measuring devices may also be used alone or in
combination.
[0022] The measuring devices 108 provide the readings to a
transmitter 110. In some embodiments, the transmitter 110 provides
the readings to a receiver 113. In other embodiments, the
transmitter 110 receives the readings and determines whether a lift
or a non-lift has occurred. The determination of whether the lift
or non-lift has occurred may then be stored on the transmitter 110
for later reading by an administrator of the facility in which the
system 100 is deployed. The determination may, in some embodiments,
be communicated to a monitoring computing device 106.
[0023] The transmitter 110 may be attached to, integrated with, or
otherwise coupled to the electro-mechanical patient lift 102. The
transmitter 110 may be separate from or integrated with one or more
of the measuring devices 108. The transmitter 110 may communicate
through a wired or wireless medium. For example, the transmitter
110 may send information in a facility at a certain frequency. An
example of the transmitter 110 is the INOVONICS EE1212 dual input
universal transmitter by Inovonics Wireless Corporation. However,
other types of transmitters with a differing number of inputs may
also be used.
[0024] In some embodiments, one or more repeaters 112 are used with
the system 100 to provide the readings and/or other information
from the transmitter 110 to a receiver 113. An example of the
repeater 112 is the INOVONICS EN5040 by Inovonics Wireless
Corporation. However, other types of repeaters may also be used.
Multiple repeaters 112 may be deployed in a facility to ensure that
the receiver 113 ultimately receives the information.
[0025] In one embodiment, a repeater 112 may be coupled to a
locator. The locator may add a location identifier to a received
signal that may be used to identify the location of the transmitter
110.
[0026] In some embodiments, the receiver 113 receives readings made
by the measuring devices 108 and/or results of determinations made
by the transmitter 110, and provides the information to the
monitoring computing device 106.
[0027] The receiver 113 is coupled to the monitoring computing
device 106. For example, the receiver 113 may be a 9 pin serial
receiver that is physically and electronically connected to the
monitoring computing device 106 through a serial card. In one
particular embodiment, the receiver 113 is the INOVONICS EN6040 by
Inovonics Wireless Corporation. In some embodiments, the monitoring
computing device 106 is located inside the facility in which the
electro-mechanical patient lifts 102 are located. In other
embodiments, the monitoring computing device 106 is located outside
the facility (e.g., a separate monitoring center or as a remote
server).
[0028] The transmitter 110 and/or the receiver 113 may include a
counter to record a number of lifts that have been performed by the
electro-mechanical patient lift 102. In some embodiments, the
number indicated by the counter may be read by an administrator and
reset without providing the number of lifts to the monitoring
computing device 106. In other embodiments, the number indicated by
the counter is provided to the monitoring computing device 106.
[0029] The monitoring computing device 106 may store the readings
and/or determinations as lift data 116 from a number of
electro-mechanical patient lifts 102 (e.g., of a facility) in a
database 114. The monitoring computing device 106 may receive
readings and determine whether a lift or non-lift has occurred. The
monitoring computing device 106 may receive a count on a number of
lifts and/or non-lifts performed by the electro-mechanical patient
lift 102. The results of the determination and/or the counts may be
stored as the lift data 116.
[0030] Examples of the monitoring computing device 106 include a
set-top box, a gaming unit, a receiver card, a set-top box (STB) a
mobile phone, a personal digital assistant (PDA), a display device,
a generic computing system, or the like. Other devices may also be
used.
[0031] The monitoring computing device 106 may use the lift data
116 to generate one or more report message (e.g., regarding lifts
that have been performed in a certain geographic area). In one
embodiment, the monitoring computing device 106 may archive the
lift data 116 for later reporting.
[0032] An administrator device 118 may receive some or all of these
report messages from the monitoring computing device 106. The
administrator device 118 may be a computing device, pager, cell
phone, or other electronic device operated by an administrator to
obtain information regarding the operation of the system 100. For
example, the administrator may use the report messages received to
determine that certain electro-mechanical patient lifts 102 are not
being used or not being used properly. In one embodiment, the
administrator may receive the report messages real time in an
email.
[0033] The administrator is a person that may use information about
operation of the lifts that occurred in a facility (or multiple
facilities). For example, the administrator may be a single person
in charge of a facility or the operations of some portion of the
facility. Multiple administrators may include staff personnel of a
facility that may receive the same information or different
information depending on particular settings of the monitoring
computing device 106. Other examples of administrators include unit
managers, department managers, risk managers, or the like.
[0034] The report messages may be transmitted over a network 104
from the computer monitoring device 106 to the administrator device
118. Examples of the network 104 include Mobile Communications
(GSM) network, a code division multiple access (CDMA) network, 3rd
Generation Partnership Project (3GPP), an Internet Protocol (IP)
network, a Wireless Application Protocol (WAP) network, a WiFi
network, or an IEEE 802.11 standards network, as well as various
combinations thereof. Other conventional and/or later developed
wired and wireless networks may also be used.
[0035] By way of an example, an administrator may log into the
monitoring computing device 106 during a shift change, identify the
patients that need lift assistance (and their associated rooms),
and determine whether lift assistance was provided to these
patients using the electro-mechanical patient lifts 102. The
administrator may ignore rooms and/or patients that are not in need
of lift assistance.
[0036] FIG. 2 illustrates an example transmitter 110, according to
an example embodiment. The transmitter 110 is shown to include a
lift monitoring subsystem 202. The lift monitoring subsystem 202
receives readings from the measuring devices 108 and determines
whether a patient lift has occurred. The transmitter 110 with the
lift monitoring subsystem 202 may be deployed in the system 100, or
may be deployed in another system.
[0037] FIG. 3 illustrates an example monitoring computing device
106, according to an example embodiment. The monitoring computing
device 106 is shown to include a lift monitoring subsystem 202. The
monitoring computing device 106 with the lift monitoring subsystem
202 may be deployed in the system 100, or may be deployed in
another system.
[0038] In some embodiments, the lift monitoring subsystem 202 may
be included in both the transmitter 110 and the monitoring
computing device 106, while in other embodiments, the lift
monitoring subsystem 202 is included in only one of the devices. In
yet another embodiment, a portion of the lift monitoring subsystem
202 is included in the transmitter 110 and a remaining portion is
included in the monitoring computing device 106. Other
configurations may also be used.
[0039] FIG. 4 illustrates an example lift monitoring subsystem 400
that may be deployed as the lift monitoring subsystem 202 in the
monitoring computing device 106, the transmitter 110, or otherwise
deployed in another system. One or more modules are communicatively
coupled and included in the lift monitoring subsystem 400 to enable
monitoring of the electro-mechanical patient lift 102. The modules
of the lift monitoring subsystem 400 that may be included are a
designation receiver module 402, an operation signal receiver
module 404, a transmitter identifier receiver module 406, a
location module 408, a signal measurement module 410, a load
measurement module 412, a lift qualification module 414, and a
recordation module 416. Other modules may also be included. In some
embodiments, the modules of the lift monitoring subsystem 400 may
be distributed so that some of the modules are deployed in the
monitoring computing device 106 and others are deployed in the
transmitter 110. In one particular embodiment, the lift monitoring
subsystem 400 includes a processor, memory coupled to the
processor, and a number of the aforementioned modules deployed in
the memory and executed by the processor.
[0040] In some embodiments, the designation receiver module 402
receives a threshold designation. The threshold designation is
typically received by an administration of the facility and
designates certain time thresholds that are enforced in order to
qualify a certain activity using the electro-mechanical patient
lift 102 as a lift. The threshold designation may include an up
time threshold, a down time threshold, and/or a delay time ceiling.
The up time threshold indicates an amount of time that the
electro-mechanical patient lift 102 is operated in an up position.
The down time threshold indicates an amount of time that the
electro-mechanical patient lift 102 is operated in a down position.
The delay time ceiling indicates a maximum amount of time between
the operation of the electro-mechanical patient lift 102 in the up
position and the operation of the electro-mechanical patient lift
102 in the down position. Other thresholds may also be
designated.
[0041] When the electro-mechanical patient lift is being operated
in a first position (e.g., an up position), the operation signal
receiver module 404 receives a first operation signal from a first
relay. Relays are a type of measuring device 108 that may be used
with the system 100. The operation signal receiver module 404 also
receives a second operation signal from a second relay when the
electro-mechanical patient lift 102 is being operated in a second
position (e.g., a down position).
[0042] In some embodiments, the transmitter identifier receiver
module 406 receives a transmitter identifier when the
electro-mechanical patient lift 102 is being operated. The
transmitter identifier may be provided with the operation signals,
or may be separately provided. For example, the transmitted
identifier may be provided simultaneously with the operation
signals, before the operation signals are provided, or after the
operation signals were provided. In other embodiments wherein the
electro-mechanical patient lift 102 is an overhead patient lift,
the electro-mechanical patient lift 102 may be hardwired to the
monitoring computing device 106. The monitoring computing device
106 may then identify the particular electro-mechanical patient
lift 102 based on exact knowledge of which of many
electro-mechanical patient lifts 102 of a facility that provided a
reading.
[0043] In some embodiments, the location module 408 is deployed in
the lift monitoring subsystem 400 to identify a location associated
with the transmitter identifier and/or receive positional data
associated with a location of the electro-mechanical patient lift
102. The positional data may be received from a Global Positioning
System (GPS) receiver, a tag associated with the electro-mechanical
patient lift 102, a tag associated with an operator using the
electro-mechanical patient lift 102, or the like.
[0044] When included in the example lift monitoring subsystem 400,
the signal measurement module 410 measures signal duration of the
operation signals to identify how long the electro-mechanical
patient lift 102 is operated in the first position and the second
position. In other embodiments, time between signal measurements is
used.
[0045] In some embodiments, load measurement is received from a
load sensor by the load measurement module 412 to determine whether
the load measurement meets a load threshold. The load threshold is
an amount of load on the electro-mechanical patient lift 102 that
qualifies whether a lift has been made. Use of a load threshold may
reduce the amount of non-lifts that are qualified as lifts. The
designation of the load threshold may be received by the
designation receiver module 402, or may be otherwise set.
[0046] The lift qualification module 414 determines whether a lift
qualification threshold is met (e.g., based on receipt of operation
signals). In one embodiment, the lift qualification threshold is
one or more qualifications (e.g., amount, type and/or duration) of
one or more signals to be received that are designated as being
sufficient to qualify a reading as being a lift. For example, the
lift qualification threshold may designate a reading as being a
lift when the electro-mechanical patient lift 102 is operated in
the up position for at least five seconds and operated in the down
position for at least five seconds. The lift qualification may be
hard-coded (e.g., by a manufacturer), or may be designated from
time to time by an administrator of a facility or other person. In
some embodiments, lift qualification module 414 determines whether
the lift qualification threshold is met based on the operations
signal and a determination that the load measurement meets the load
threshold.
[0047] The recordation module 416 records an occurrence of a lift
when a determination is made that the lift qualification threshold
is met. In some embodiments, the recordation module 416 records the
transmitter identifier with the occurrence of the lift. In other
embodiments, the recordation module 416 records the location with
the occurrence of the lift. In some embodiments, the recordation
module 416 records an occurrence of a non-lift when a determination
is made that the lift qualification threshold is not met. The
recordation of the lifts may be made as the lift data 116 in the
database 114 (see FIG. 1).
[0048] FIG. 5 illustrates an example lift monitoring subsystem 500
that may be deployed as the lift monitoring subsystem 202 in the
monitoring computing device 106, the transmitter 110, or otherwise
deployed in another system. One or more modules are communicatively
coupled and are included in the lift monitoring subsystem 500 to
enable monitoring of the electro-mechanical patient lift 102. The
modules of the lift monitoring subsystem 500 that may be included
are a current assessment module 502, a measurement receiver module
504, a difference calculation module 506, a transmitter identifier
receiver module 508, a battery power condition assessment module
510, a lift qualification module 512, a recordation module 514, a
report message transmitter module 516, and/or a compliance module
518. Other or different modules may also be included. In some
embodiments, the modules of the lift monitoring subsystem 500 may
be distributed so that some of the modules are deployed in the
monitoring computing device 106 and others are deployed in the
transmitter 110. In some embodiments, the modules of the lift
monitoring subsystem 400 may be included with the modules of the
lift monitoring subsystem 500, or the lift monitoring subsystem 500
may be included with the modules of the lift monitoring subsystem
400. In one particular embodiment, the lift monitoring subsystem
500 includes a processor, memory coupled to the processor, and a
number of the aforementioned modules deployed in the memory and
executed by the processor.
[0049] In general, the lift monitoring subsystem 500 uses a current
sensor as the measuring device 108 instead of the relays used by
the lift monitoring subsystem 400. The lift monitoring subsystem
500 may be used instead of or in addition to the lift monitoring
subsystem 400. Other lift monitoring subsystems that include
different measuring devices 108 may also be used.
[0050] In some embodiments, the current assessment module 502
accesses a non-usage current associated with the electro-mechanical
patient lift 102. The non-usage current is an amount of current
flowing through the electro-mechanical patient lift 102 when the
electro-mechanical patient lift 102 is not in operation. In some
embodiments, the designation receiver module 402 may receive the
amount of the non-current usage.
[0051] The measurement receiver module 504 receives a measurement
of current from a current sensor coupled to the electro-mechanical
patient lift 102. The difference calculation module 506 calculates
a current difference between the measurement of current and the
non-usage current.
[0052] The transmitter identifier receiver module 508 receives a
transmitter identifier from the transmitter 110 (see FIG. 1). The
battery power condition assessment module 510 assesses a battery
power condition of a lift battery used by the electro-mechanical
patient lift 102. The battery power condition may be affected based
on a current operation being performed by the electro-mechanical
patient lift 102, past use of the electro-mechanical patient lift
102, age of the lift battery, or the like.
[0053] The lift qualification module 512 determines whether a lift
qualification threshold is met. In some embodiments, the
determination is made based on receipt of the measurement of
current. In other embodiments, the determination is made based on
the current difference meeting the lift qualification threshold. In
some embodiments, the determination includes assessment of the
battery power condition.
[0054] The recordation module 514 records an occurrence of a lift
when a determination is made that the lift qualification threshold
is met. In some embodiments, the transmitter identifier is recorded
with the occurrence of the lift.
[0055] The report message transmitter module 516 transmits a report
message to the administrator device 118. The report message may
include information associated with the recording of the occurrence
of the lift. The report message may include a lift usage
confirmation of the electro-mechanical patient lift 102 and/or of
an additional electro-mechanical patient lift, a lift nonuse
notification of the electro-mechanical patient lift 102 and/or of
an additional electro-mechanical patient lift, or the like.
[0056] In some embodiments, the report message transmitter module
516 is deployed in the lift monitoring subsystem 400. In some
embodiments, the designation receiver module is deployed in the
lift monitoring subsystem 500. Other variations on the inclusion
and coupling of modules in the lift monitoring subsystems 400, 500
may be used.
[0057] FIG. 6 illustrates an example lift monitoring subsystem 600
that may be deployed as the lift monitoring subsystem 202 in the
monitoring computing device 106, the transmitter 110, or otherwise
deployed in another system. One or more modules are communicatively
coupled and are included in the lift monitoring subsystem 600 to
enable monitoring of the electro-mechanical patient lift 102. The
modules of the lift monitoring subsystem 600 that may be included
are a baseline lift data module 602, a value determination module
604, a lift determination module 606, a comparison module 608, a
value modification module 610, an updating module 612, a signal
receiver module 614, a timing identification module 616, a
recordation module 618, and/or a qualification threshold module
620. Other or different modules may also be included. In some
embodiments, the modules of the lift monitoring subsystem 600 may
be distributed so that some of the modules are deployed in the
monitoring computing device 106 and others are deployed in the
transmitter 110. In some embodiments, the modules of the lift
monitoring subsystem 400, 500 may be included with the modules of
the lift monitoring subsystem 600, or the lift monitoring subsystem
600 may be included with the modules of the lift monitoring
subsystems 400, 500. In one particular embodiment, the lift
monitoring subsystem 600 includes a processor, memory coupled to
the processor, and a number of the aforementioned modules deployed
in the memory and executed by the processor.
[0058] In some embodiments, the baseline lift data module 602
accesses baseline lift data of a patient facility and the value
determination module 604 determines a compliance value based on the
baseline lift data.
[0059] The lift determination module 606 determines a number of
patient lifts performed during a time period in an area of a
patient facility.
[0060] The comparison module 608 compares the number of patient
lifts performed to a compliance value.
[0061] The value modification module 610 modifies the compliance
value based on a result of comparison between the number of patient
lifts performed to the compliance value.
[0062] In some embodiments, the value modification 610 module
receives a compliance adjustment from a user and modifies the
compliance value based on the result of comparison between the
number of patient lifts performed to the compliance value and
receipt of the compliance adjustment.
[0063] The updating module 612 updates the baseline data based on
the number of patient lifts performed during the time period.
[0064] The signal receiver module 614 receives signals from
measuring devices coupled to an electro-mechanical patient
lift.
[0065] The timing identification module 616 identifies lift usage
timing based on receipt of a single signal or multiple signals.
[0066] The recordation module 618 records lift usage data based on
receipt of the signal and identification of the lift usage
timing.
[0067] In some embodiments, the qualification threshold module 620
determines whether a lift qualification threshold is met based on
receipt of the signal and the identification of the lift usage
timing and the recordation module 618 records an occurrence of a
lift when a determination is made that the lift qualification
threshold is met.
[0068] In some embodiments, the timing identification module 616
identifies total lift usage timing during a time period for
electro-mechanical patient lifts based on lift usage data for the
electro-mechanical patient lift and the comparison module 608
compares total lift usage timing to a compliance value.
[0069] FIG. 7 illustrates a method 700 for lift monitoring
according to an example embodiment. The method 700 may be performed
by the monitoring computing device 106, the transmitter 110 of the
system 100 (see FIG. 1), or may be otherwise performed.
[0070] A threshold designation may be received at block 702. The
threshold designation may include an up time threshold, a down time
threshold, and/or a delay time ceiling. The threshold may also
include other designations.
[0071] At block 704, a first operation signal is received from a
first relay coupled to the electro-mechanical patient lift 102 when
the electro-mechanical patient lift 102 is being operated in a
first position (e.g., an up position).
[0072] At block 706, a second operation signal is received from a
second relay coupled to the electro-mechanical patient lift 102
when the electro-mechanical patient lift 102 is being operated in a
second position (e.g., a down position).
[0073] In some embodiments, a transmitter identifier is received
from the transmitter 110 at block 708 when the electro-mechanical
patient lift 102 is being operated.
[0074] At decision block 710, a determination of whether a lift
qualification threshold is met based on receipt of the first
operation signal and the second operation signal. In some
embodiments, the determination is based on receipt of the first
operation signal, the second operation signal, and the designation
of the up time threshold, the down time threshold, and/or the delay
ceiling.
[0075] In some embodiments, a load measurement is received from a
load sensor coupled to the electro-mechanical patient lift 102 and
a determination of whether the load measurement meets a load
threshold is made. The determination of whether the lift
qualification threshold is met is then made at decision block 710
based on receipt of the first operation signal and the second
operation signal and a determination that the load measurement
meets the load threshold.
[0076] In some embodiments, a first signal duration of receiving
the first operation signal is measured and a second signal duration
of receiving the second operation signal is measured. The
determination of whether the lift qualification threshold is met is
then made at decision block 710 based on a determination of whether
the first signal duration meets the up time threshold and a
determination of whether the second signal duration meets the down
time threshold.
[0077] If the determination is made that the lift qualification
threshold is met, an occurrence of a lift is recorded at block 712.
In some embodiments, the transmitter identifier is recorded at
block 714 with the occurrence of the lift.
[0078] If a determination is made that the lift qualification
threshold is not met at decision block 710, an occurrence of a
non-lift is recorded at block 716. In some embodiments, the
transmitter identifier is recorded at block 714 with the occurrence
of the non-lift.
[0079] In some embodiments, a location associated with the
transmitter identifier is identified and the location is recorded
with the occurrence of the lift or non-lift. In other embodiments,
positional data associated with a location of the
electro-mechanical patient lift 102 is received and the location is
recorded with the occurrence of the lift or non-lift.
[0080] FIG. 8 illustrates a method 800 for lift monitoring
according to an example embodiment. The method 800 may be performed
by the monitoring computing device 106, the transmitter 110 of the
system 100 (see FIG. 1), or may be otherwise performed.
[0081] A non-usage current associated with the electro-mechanical
patient lift 102 is accessed at block 802. A measurement of current
from a current sensor coupled to the electro-mechanical patient
lift 102 is received at block 804.
[0082] A calculation of a current difference between the
measurement of current and the non-usage current is made at block
806. In some embodiments, a transmitter identifier is received from
the transmitter 110 at block 808.
[0083] A battery power condition of a lift battery of the
electro-mechanical patient lift 102 may be accessed at block
810.
[0084] At decision block 812, a determination of whether a lift
qualification threshold is met based on receipt of the measurement
of current is made. The determination of the whether the lift
qualification threshold is met may be based on the current
difference meeting the lift qualification threshold. In some
embodiments, the determination of whether the lift qualification
threshold is met is based on receipt of the measurement of current
change and assessment of the battery power condition.
[0085] In an example embodiment, a threshold designation may be
received prior to the operations performed at decision block 812.
The threshold designation may include a certain battery condition
and/or a specified amount of current difference that may be used to
determine whether lift qualification threshold. The threshold may
also include other designations.
[0086] If the determination is made that the lift qualification
threshold is met, an occurrence of a lift is recorded at block 814.
In some embodiments, the transmitter identifier is recorded at
block 816 with the occurrence of the lift.
[0087] If a determination is made that the lift qualification
threshold is not met at decision block 812, an occurrence of a
non-lift is recorded at block 818. The transmitter identifier may
be recorded at block 816 with the occurrence of the non-lift. In
some embodiments, the report message regarding the occurrences of
lifts and non-lifts is transmitted to an administrator through the
administrator device 118 (see FIG. 1) at block 820.
[0088] In an example embodiment, the report message transmitted at
block 820 may also be transmitted after the completions of the
operations at block 712, block 714, and/or block 716 (see FIG.
7).
[0089] The report message may be transmitted hourly, daily, weekly,
monthly, quarterly, or at some other time increment. The report
message may include information regarding all occurrences of lifts
and/or non-lifts, or a subset of the number of occurrences. For
example, only the occurrences of lifts on particular
electro-mechanical patient lifts 102 in a particular facility may
be reported. The information provided in the report message may
include aggregate information regarding the lifts and/or non-lifts,
or more detailed information may be provided. For example, certain
electro-mechanical patient lifts 102 may be identified in the
report message, or the report message may include aggregated
information about a certain number or grouping of
electro-mechanical patient lifts 102.
[0090] By way of an example, if there are twelve rooms in a
particular ward of a facility and four of those rooms have patients
that need lift assistance, the report message may be sent to the
department manager's phone at the end of the shift confirming the
electro-mechanical patient lifts 102 were used in those rooms and
how many lifts/transfers were performed. The department manager may
be provided with crucial information on nonuse of certain of the
electro-mechanical patient lifts 102 so that the manager may
immediately communicate with staff and immediately rectify the
problem. That same information may also be sent to a risk manager
that may have the ultimate responsibility for the whole facility.
If, as an example, the risk manager sees from the information that
three of the twelve departments are not utilizing the potential of
their lift equipment properly, automatically notifications of the
noncompliance may be sent to immediately let the department
managers know that this occurred and to timely rectify the
problem.
[0091] FIG. 9 illustrates a method 900 for lift monitoring
according to an example embodiment. The method 900 may be performed
by the monitoring computing device 106, the transmitter 110 of the
system 100 (see FIG. 1), or may be otherwise performed.
[0092] A signal is received from a measuring device coupled to an
electro-mechanical patient lift at block 902.
[0093] An additional signal may be received at block 904. In some
embodiments, the additional signal is received from the measuring
device at a different time than the signal. In some embodiments,
the additional signal is received from an additional measuring
device coupled to the electro-mechanical patient lift at a
different time than the signal.
[0094] Lift usage timing is identified at block 906 based on
receipt of the signal. In some embodiments, identification of the
lift usage timing may be based on receipt of the signal and the
additional signal.
[0095] Lift usage data is recorded at block 908 based on receipt of
the signal and identification of the lift usage timing. In some
embodiments, recordation of the lift usage data is based on receipt
of the signal and the additional signal and identification of the
lift usage timing.
[0096] In some embodiments, a determination of whether a lift
qualification threshold is met is based on receipt of the signal
and the identification of the lift usage timing. The recording of
the lift usage data may then include recording an occurrence of a
lift when a determination is made that the lift qualification
threshold is met.
[0097] Total lift usage timing during a time period may be
identified for a electro-mechanical patient lifts at block 910
based on lift usage data for the electro-mechanical patient
lifts.
[0098] A comparison of total lift usage timing to a compliance
value may be made at block 912.
[0099] The compliance value may be modified at block 914 based on a
result of comparison between the total lift usage timing and the
compliance value.
[0100] The baseline data may be updated at block 1016 based on the
number of patient lifts performed during the time period.
[0101] FIG. 10 illustrates a method 1000 for lift monitoring
according to an example embodiment. The method 1000 may be
performed by the monitoring computing device 106, the transmitter
110 of the system 100 (see FIG. 1), or may be otherwise
performed.
[0102] Baseline lift data of a patient facility may be accessed at
block 1002. The baseline lift data is associated with the
electro-mechanical patient lifts in a patient facility. In some
embodiments, the baseline lift data is accessed from the database
116. In other embodiments, the baseline lift data is received
through a user interface.
[0103] A compliance value may be determined at block 1004 based on
the baseline lift data. In some embodiments, the compliance value
is associated with a targeted number of patient lift tasks to be
performed in the area. In some embodiments, the compliance value
may be associated with multiple lift types to be performed. In some
embodiments, the compliance value is a compliance percentage. For
example, the compliance value may be a percentage of a
predetermined number of expected patient lifts.
[0104] The area may be the entire patient facility, a portion of
the patient facility. The area may include a number of rooms of the
patient facility.
[0105] A number of patient lifts performed during a time period in
an area of a patient facility is determined at block 1006. The
patient facility includes electro-mechanical patient lifts.
[0106] In some embodiments, the determination of the number of
patient lifts performed is based on the baseline lift data and
recorded lift usage data from at least a portion of the
electro-mechanical patient lifts.
[0107] A comparison of the number of patient lifts performed to a
compliance value may be made at block 1008.
[0108] At block 1010, modification of the compliance value is made
based on a result of comparison between the number of patient lifts
performed to the compliance value. The modification may include
increasing or decreasing the compliance value. For example, if the
number of patient lifts performed is greater than the compliance
value, then the compliance value may be incrementally
increased.
[0109] In some embodiments, a compliance adjustment may be received
from a user and modification to the compliance value may be made
based on the result of a comparison between the number of patient
lifts performed to the compliance value and receipt of the
compliance adjustment.
[0110] FIG. 11 is a diagram of an example measurement device
configuration 1100, according to an example embodiment. The
measurement device configuration 1100 may be used with the system
100 (see FIG. 1), or may be otherwise used.
[0111] The measurement device configuration 1100 includes
connectors 1102, 1104 that are coupled to the electro-mechanical
patient lift 102 (see FIG. 1). The connectors 1102, 1104 may be
connected to actuators of the electro-mechanical patient lift 102,
or may be otherwise coupled. The information (e.g., an amount of
voltage) obtained from the electro-mechanical patient lift 102 by
the connectors 1102, 1104 and is passed through a terminal strip
1106 and diodes 1108, 1110.
[0112] The information provided by the connectors 1102, 1104, is
then received by relays 1112, 1114 and used by the relays 1112,
1114 to make a reading.
[0113] As shown, the connectors 1102, 1104, are coupled to positive
and negative terminals of the terminal strip 1106. The negative
terminal of the terminal strip 1106 is coupled to the negative
terminal of a relay 1112 and through a diode 1110 to the negative
terminal of a relay 1114. The positive terminal of the terminal
strip 1106 is coupled through a diode 1108 to a positive terminal
of the relay 1112 and to the positive terminal of the relay
1114.
[0114] The readings made by the relays 1112, 1114 are then passed
through the terminal strip 1106 to transmitters 1116, 1118. The
transmitters 1116, 1118 may be two separate transmitters, or may be
two separate inputs on a single transmitter.
[0115] As shown, a com terminal of the relay 1112 is coupled to a
transmitter 1116 through a R1 comm terminal of the terminal strip
1106. A normally closed terminal of the relay 1112 is coupled to
the transmitter 1116 through a R1 normally closed terminal of the
terminal strip 1116. A com terminal of the relay 1114 is coupled to
a transmitter 1118 through a R2 comm terminal of the terminal strip
1106. A normally opened terminal of the relay 1114 is coupled to
the transmitter 1118 through a R2 normally opened terminal of the
terminal strip 1116.
[0116] Other embodiments of the measurement device configuration
1100 may include different components, different configurations,
and/or different couplings.
[0117] FIG. 12 is a diagram of an example measurement device
configuration 1200, according to example embodiment. The
measurement device configuration 1200 may be used with the system
100 (see FIG. 1), or may be otherwise used.
[0118] The measurement device configuration 1200 includes a battery
1202 of the electro-mechanical patient lift 102 (see FIG. 1)
coupled to a current sensor 1206. As shown, the current sensor 1204
is wrapped around a positive wire 1206 of the battery 1202. The
reading made by the current sensor 1204 is then provided to the
transmitter 1206.
[0119] Other embodiments of the measurement device configuration
1200 may include different components, different configurations,
and/or different couplings.
[0120] FIG. 13 is an example display 1300 of a screenshot,
according to an example embodiment. In some embodiments, the
display 1300 may be generated for a user interface to be displayed
to the administrator of the system 100.
[0121] The display 1300 may allow the administrator to add patient
lift equipment to be monitored by the monitoring computing device
106 of the monitoring system 130.
[0122] The display 1300 includes drop down menus for selecting the
type of equipment to be monitored, forms for inputting specific
equipment data, among others. Additionally, the display 1300
includes fields 1302, 1304, and 1306 for values that a patient
facility could use as a basis for determining if a lift or task has
been performed. For example, as shown in the display 1300, four
seconds "Minimum Down" and four seconds "Minimum up" with an
interval of twenty seconds between each "Minimum Down" and "Minimum
Up" would constitute the completion of a lift or a task. The
display 1300 may also include a field for the compliance set point
(CSP) or compliance value for both day and night shifts.
[0123] The display 1400 may include a selection for identification
of the manufacturer of the lift (e.g., Liko or Other Manufacture).
The associated model numbers are also available for selection. The
serial number for the electro-mechanical patient lift 102, the room
or unit to which the electro-mechanical patient lift 102 is
assigned, and a module identification associated with a serial
number of the measuring device 106 may be identified. If the
manufacture or model is unknown, the administrator may select
overhead, sit-to stand and total lift.
[0124] The basis upon which the facility wants to use to determine
if a task/lift has been performed may also be selected. For
instance, the administrator may define that a task/lift occurs with
at least four seconds up movement and four seconds of down
movement. Global settings for a unit/department of the facility may
be selected, or each particular electro-mechanical patient lift may
have its own lift criteria. The administrator may also pick the
interval between the first and the latter movement. For instance,
if the electro-mechanical patient lift goes up or down for four
seconds but then the interval time expires, the lift or task may
not be recorded. Also, in the display may allow selection of how
much time the lift is unused before lift data is stored or someone
is notified regarding the activity.
[0125] FIG. 14 is an example display 1400 of a screenshot,

training request. The training request may specify the unit in
which the electronic mechanical patient lift 102 is located, the
administrator submitting the repair request, and comments provided
by the administrator. In some embodiments, the training request may
be generated for display based on low achievement with a compliance
set point.
[0131] FIG. 17 is an example display 1700 of a screenshot,
according to an example embodiment. In some embodiments, the
display 1700 may be generated for a user interface to be displayed
to the administrator of the system 100.
[0132] In general, the display 1700 may be used to automatically
transmit a maintenance request to maintenance personnel regarding
the use of a ceiling electronic mechanical patient lift 102. In
some embodiments, the maintenance request may be generated for

to the administrator of the system 100.
[0135] In general, the display 1900 may be used to request
additional information from the administrator regarding usage below
a compliance set point. As shown in the display 1900, information
regarding the rooms, the area, and the reason for being below the
compliance set point may be identified.
[0136] In some embodiments, the displays 1900, 2000 may be used to
initiate preventative maintenance for the electro-mechanical
patient lift 102. The displays may then be transmitted (e.g., via
email) to the appropriate department.
[0137] In some embodiments, the displays 1900, 2000 or other
displays may include an electronic manual for the
electro-mechanical patient lift 102.
[0138] FIG. 20 shows a block diagram of a machine in the example
form of a computer system 2000 within which a set of instructions
may be executed causing the machine to perform any one or more of
the methods, processes, operations, or methodologies discussed
herein. The monitoring computing device 106, the transmitter 110,
and/or the administrator device 118 may include the functionality
of the one or more computer systems 2000.
[0139] In an example embodiment, the machine operates as a
standalone device or may be connected (e.g., networked) to other
machines. In a networked deployment, the machine may operate in the
capacity of a server or a client machine in server-client network
environment, or as a peer machine in a peer-to-peer (or
distributed) network environment. The machine may be a server
computer, a client computer, a personal computer (PC), a tablet PC,
a set-top box (STB), a Personal Digital Assistant (PDA), a cellular
telephone, a web appliance, a network router, switch or bridge, or
any machine capable of executing a set of instructions (sequential
or otherwise) that specify actions to be taken by that machine.
Further, while only a single machine is illustrated, the term
"machine" shall also be taken to include any collection of machines
that individually or jointly execute a set (or multiple sets) of
instructions to perform any one or more of the methodologies
discussed herein.
[0140] The example computer system 2000 includes a processor 2012
(e.g., a central processing unit (CPU) a graphics processing unit
(GPU) or both), a main memory 2004 and a static memory 2006, which
communicate with each other via a bus 2008. The computer system
2000 may further include a video display unit 1200 (e.g., a liquid
crystal display (LCD) or a cathode ray tube (CRT)). The computer
system 2000 also includes an alphanumeric input device 2012 (e.g.,
a keyboard), a cursor control device 2014 (e.g., a mouse), a drive
unit 2016, a signal generation device 2018 (e.g., a speaker) and a
network interface device 2020.
[0141] The drive unit 2016 includes a machine-readable medium 2022
on which is stored one or more sets of instructions (e.g., software
2024) embodying any one or more of the methodologies or functions
described herein. The software 2024 may also reside, completely or
at least partially, within the main memory 2004 and/or within the
processor 2012 during execution thereof by the computer system
2000, the main memory 2004 and the processor 2012 also constituting
machine-readable media.
[0142] The software 2024 may further be transmitted or received
over a network 2026 via the network interface device 2020.
[0143] While the machine-readable medium 2022 is shown in an
example embodiment to be a single medium, the term
"machine-readable medium" should be taken to include a single
medium or multiple media (e.g., a centralized or distributed
database, and/or associated caches and servers) that store the one
or more sets of instructions. The term "machine-readable medium"
shall also be taken to include any medium that is capable of
storing or encoding a set of instructions for execution by the
machine and that cause the machine to perform any one or more of
the methodologies of the present invention. The term
"machine-readable medium" shall accordingly be taken to include,
but not be limited to, solid-state memories, and optical media, and
magnetic media. In one embodiment, the machine-readable medium is a
non-transitory machine-readable medium.
[0144] Certain systems, apparatus, applications or processes are
described herein as including a number of modules. A module may be
a unit of distinct functionality that may be presented in software,
hardware, or combinations thereof. When the functionality of a
module is performed in any part through software, the module
includes a machine-readable medium. The modules may be regarded as
being communicatively coupled.
[0145] The inventive subject matter may be represented in a variety
of different embodiments of which there are many possible
permutations.
[0146] In an example embodiment, a first operation signal may be
received from a first relay coupled to an electro-mechanical
patient lift when the electro-mechanical patient lift is being
operated in a first position. A second operation signal may be
received from a second relay coupled to the electro-mechanical
patient lift when the electro-mechanical patient lift is being
operated in a second position. A determination of whether a lift
qualification threshold is met based on receiving the first
operation signal and the second operation signal may be made. An
occurrence of a lift may be recorded when a determination is made
that the lift qualification threshold is met.
[0147] In an example embodiment, a measurement of current may be
received from a current sensor coupled to an electro-mechanical
patient lift. A determination of whether a lift qualification
threshold is met based on receipt of the measurement of current. An
occurrence of a lift may be recorded when a determination is made
that the lift qualification threshold is met.
[0148] In an example embodiment, a wireless transmitter may be
coupled to an electro-mechanical patient lift. A first relay and a
second relay may be coupled to the wireless transmitter and the
electro-mechanical patient lift. The first relay may activate when
the electro-mechanical patient lift is being used in an up position
and the second relay activates when the electro-mechanical patient
lift is being used in a down position. The wireless transmitter may
detect activation of the first relay and the second relay. The
information regarding the activation of the first relay and the
second relay may be sent to a monitoring computer device.
[0149] In an example embodiment, a wireless transmitter may be
coupled to an electro-mechanical patient lift. A current sensor may
be coupled to the wireless transmitter and the electro-mechanical
patient lift. The current sensor may receive a measurement of
current change from a current sensor coupled to a battery of the
electro-mechanical patient lift and may provide the measurement to
the wireless transmitter. The wireless transmitter may receive the
measurement and transmit information including the measurement to a
monitoring computer device.
[0150] In an example embodiment, an operation signal receiver
module may receive a first operation signal from a first relay
coupled to an electro-mechanical patient lift when the
electro-mechanical patient lift is being operated in a first
position and to receive a second operation signal from a second
relay coupled to the electro-mechanical patient lift when the
electro-mechanical patient lift is being operated in a second
position. A lift qualification module may determine whether a lift
qualification threshold is met based on the receiving of the first
operation signal and the second operation signal. A recordation
module may record an occurrence of a lift when a determination is
made that the lift qualification threshold is met.
[0151] In an example embodiment, a measurement receiver module may
receive a measurement of current from a current sensor coupled to
an electro-mechanical patient lift. A lift qualification module may
determine whether a lift qualification threshold is met based on
the receiving of the measurement of current. A recordation module
may record an occurrence of a lift when a determination is made
that the lift qualification threshold is met.
[0152] In an example embodiment, a determination of a number of
patient lifts performed during a time period in an area of a
patient facility may be made. The patient facility may include a
plurality of electro-mechanical patient lifts. A comparison the
number of patient lifts performed to a compliance value may be
performed. The compliance value may be modified based on a result
of comparison between the number of patient lifts performed to the
compliance value. The baseline data may be updated based on the
number of patient lifts performed during the time period.
[0153] In an example embodiment, a signal may be received from a
measuring device coupled to an electro-mechanical patient lift.
Lift usage timing may be identified based on receipt of the signal.
Lift usage data may be record based on receipt of the signal and
identification of the lift usage timing.
[0154] Thus, methods and systems for lift monitoring have been
described. Although embodiments of the present invention have been
described with reference to specific example embodiments, it will
be evident that various modifications and changes may be made to
these embodiments without departing from the broader spirit and
scope of the embodiments of the invention. Accordingly, the
specification and drawings are to be regarded in an illustrative
rather than a restrictive sense.
[0155] The methods described herein do not have to be executed in
the order described, or in any particular order. Moreover, various
activities described with respect to the methods identified herein
can be executed in serial or parallel fashion. Although "End"
blocks are shown in the flowcharts, the methods may be performed
continuously.
[0156] The Abstract of the Disclosure is provided to comply with 37
C.F.R. .sctn. 1.72(b), requiring an abstract that will allow the
